This report, generated from Hospital Episode Statistics (HES) A&E data, sets out data coverage, data quality and performance information for the following five A&E indicators:

• Left department before being seen for treatment rate
• Re-attendance rate
• Time to initial assessment
• Time to treatment
• Total time in A&E

Publishing these data will help share information on the quality of care of A&E services to stimulate the discussion and debate between patients, clinicians, providers and commissioners, which is needed in a culture of continuous improvement.

The data used in these reports are sourced from Provisional A&E HES data, and as such these data may differ to information extracted directly from Secondary Uses Service (SUS) data, or data extracted directly from local patient administration systems. Provisional HES data may be revised throughout the year. 

Key Facts

• A&E HES data contains 1.61 million A&E attendances for September 2017 at all types of A&E. However, A&E HES data are incomplete; over 1.76 million A&E attendances were reported in the Department of Health Situation Report data collection for the month, and 57 organisations that report data to Situation Reports did not report data to A&E HES; these organisations are mostly lower acuity services such as minor injury units and walk-in centres.

• Several organisations reported data that did not meet the data quality checks required by A&E indicators. The 95th percentile and longest single wait information are particularly sensitive to poor data quality, outliers and data definitional issues,

• Ten providers have submitted some or all of their September A&E activity to the new to the new Emergency Care Data Set, ECDS (CDS 011), in place of the standard A&E data (CDS 010). However there is an issue with mapping the ECDS data back into the standard A&E format. This has resulted in 26,454 (1.6 per cent) records (ECDS) to be missing from September in A&E HES.which contributes to why some unusually high values may be observed for these measures.

• Nationally, 3.2 per cent of attendances at A&E departments were recorded as having left A&E before being seen for treatment, and 8.0 per cent of attendances in A&E in September 2017 were unplanned re-attendances within 7 days of a previous attendance.

• The median average time to initial assessment for attendances brought to A&E by ambulance was 7 minutes, with 95 per cent of patients being assessed within 84 minutes. For all patients receiving treatment, the median average time to treatment was 58 minutes with 95 per cent of patients receiving treatment within 3 hours 25 minutes.

• The median average total time in A&E for all patients was 2 hours 28 minutes, with 95 per cent of patients departing A&E within 7 hours 00 minutes of arrival.
